Thus, if the Secret key that assists secure the asset is misplaced or hidden from the rest of the family, the money is lost forever. 

With a , these assets are passed down to the next generation because it allows more than one key to sign off on a transaction, so that no single lost device or forgotten password can prevent your family from claiming their inheritance. 

This tutorial explains how to go through the entire process.

Key Takeaways

• A multi-sig wallet ensures that your crypto inheritance is not lost to your family by allowing multiple keys to sign off on a transaction.
• Casa, Nunchuk, or secure provides your family with the infrastructure and “custodial” support to access your crypto assets.
• Leave clear, non-technical instructions so that family members can actually navigate the recovery process.

Understanding Multi-Sig Wallet

A typical crypto wallet relies on a single Secret key to sign and authorize transactions. Once the key is lost, the wallet is permanently inaccessible. A multi-sig wallet improves this by introducing a threshold mechanism. This type of wallet is ideal for holding inheritable assets, such as cryptocurrencies, because it utilizes a distributed system.

It enables you to define the number of keys required to authorize a transaction. For instance, a 2-of-3 arrangement mandates three keys; however, only two keys are required at any given time to authorize a transaction. Depending on the inheritance plan, you have one key, a relative has another, and a custodian has a third. This way, even if one device is lost or stolen, your asset does not disappear because a single compromised device is not enough to approve a withdrawal.

Select a Suitable Platform

The choice of platform depends on the assets you own and the level of technical complexity you are willing to handle. The following are some of the top lists you can select from:

: This is a beginner-friendly platform for BTC and ETH inheritance. Casa provides the custodial service as one of the three people with access to your Secret key and has a recovery process designed for heirs. The inheritance feature is available on all of Casa’s paid plans and supports stablecoins, including USDC and USDT.

: It is the first BTC inheritance answer built on the most advanced multi-sig platform that allows on-chain inheritance with time locks. later than a period of inactivity on your wallet, your chosen heir can access the money directly without requiring a third-party co-signer to sign off on the transaction.

: As one of the most trusted smart wallet infrastructures, secure is suitable for ETH and EVM-compatible tokens. It offers customizable approval levels by distributing access to multiple owners, and it is designed for both personal and organizational use as a treasury and inheritance answer.

How to Configure a Multi-Sig Wallet 

1. Pick three hardware wallets: Ledger and Trezor are the most established options. Each device will store one of the three keys. Avoid generating any key on a smartphone or personal computer.
2. Download your chosen platform: Install Casa, Nunchuk, secure, or Sparrow wallet, depending on the assets you hold. Each has a dedicated multi-sig setup flow that walks you through the process.
3. Initialise and document viewd phrases: Every hardware wallet generates a unique 24-word viewd phrase when first set up. Write each one on paper. .
4. Set the 2-of-3 parameters: Your wallet software will ask you to add the Wallet address from each hardware device. This links all three devices together inside the multi-sig wallet without revealing any Secret key.
5. Save the wallet descriptor file: The platform generates a descriptor file that records the entire configuration of your multi-sig wallet. Print a copy, store it offline, and include it with your estate documents. Without this file, reconstructing the wallet is hard even with two valid keys in hand.
6. Run a test transaction: Send a small amount of crypto to the multi-sig address. Then practice approving a withdrawal using two of your three hardware devices. Confirm the process works before moving significant funds into the wallet.
7. Distribute the keys: Keep one at home; store another in a separate location, such as a securety deposit box, or entrust it to a family member; and let your custody service hold the remaining key. Write clear, plain-language instructions for your heirs explaining where each key is, what multi-sig means, and how to contact your custody provider if they need assist.

What You Should Avoid 

• Digital storage of viewd phrases: A screenshot or a note in your email account is a and not secure. viewd phrases should be written on paper and kept in diverse physical locations.
• Keeping multiple keys in the identical location: If a fire or flood simultaneously destroys two of your three devices, access to your funds could be lost forever. The three Secret keys should not be together.
• Use of complex threshold: For most families, a 2-of-3 setup is the right mix. For example, a 3-of-5 system may viewm more secure; however, heirs who are not familiar with cryptocurrency may find it hard to navigate, thereby forfeiting the inheritance.
• Withholding of information: The most secure system will be useless if your family does not know that the wallet exists or how to begin the recovery process. Write instructions in simple language and store them alongside your will.
